According to my mother, my sister has always needed a lot of time to be alone. She gets overstimulated being in groups or out in public and needs to sit quietly for a few minutes when she gets home. Her friends love to be around her, but she always needs a few minutes at their houses where she goes into another room to sit quietly alone. She’s a great person, and we get along really well. I just know that when she says “Leave me alone,” she really means it! Which is the main idea of this paragraph?
